Question

通过简单的解决方案，可以回答类似的问题。不要以为这是一样的。首先是我的代码然后是日志。我正在使用提供的PORT env变量，但我仍然遇到此错误。

if __name__ == "__main__":
    import sys
    print( 'HELLO %s' % str(sys.argv[1]))
    #import os
    import os
    port = os.environ['PORT']
    print(port)
    cherrypy.config.update({
                        'server.socket_port': int(port),
                       })
    cherrypy.quickstart(House())

这是日志

好的，这个问题有几个问题。到目前为止，最常见的是不使用环境变量PORT中指定的端口。第二种是使用localhost或127.0.0.1（或保留默认值）指定的主机。将主机指定为0.0.0.0为我修复了它。

if __name__ == "__main__":
    import sys
    print( 'HELLO %s' % str(sys.argv[1]))
    import os
    import os
    port = os.environ['PORT']
    print(port)
    cherrypy.config.update({
                            'server.socket_host': '0.0.0.0',
                            'server.socket_port': int(port),
                           })
    cherrypy.quickstart(House())

Heroku Python Web进程无法在60秒内绑定到$ PORT - 不是显而易见的
